There is a textbook article on preoperative preparation, “psychological preparation”, which I did not understand properly when I read it at that time and thought it was redundant. Since I have been working, I have encountered some things that make me pay more and more attention to the psychological preparation of patients, especially tumor patients. When tumor patients are admitted to the hospital, before a clear diagnosis is made, most of them are anxious and worried about the malignancy, but they also have the luck that it is not malignant. So they will look anxious and need proper explanation from family members and medical care, and be psychologically prepared. For doctors we speak too lightly to such patients, the contrast between the patient after surgery and treatment is large, the patient will have some non-medical accidents, resulting in pain for the patient and family, the responsibility of the doctor and disputes. If we talk too much, we are suspected of scaring the patient and causing too much psychological pressure on the patient. Therefore, doctors are mostly confused and have a dilemma. As a doctor, we hope that the patient’s family will give strong support in the preoperative psychological preparation, not only for the good of the patient, but also to reduce the psychological pressure of the doctor, especially the surgeon in charge of the surgery patient. In medical treatment, we often encounter, admitted patients, you give him premature arrangements for surgery, the patient or family will be much doubt, is not too hasty, doctors have formed guidelines for the treatment of common diseases, early arrangements are not hasty, late arrangements are not intentional, there are certain factors of the disease patient. The doctor has the professional ethics of a doctor and cannot joke with the life of the patient.
